Intermittent wiper delay units. I am thinking of selling all my latest design Information, diagrams, printed circuit board layout and enough parts to make up 10 or 12 units less the boards. A good deal for someone with an electronic background. Over the years I've made many improvements to my units. My circuit will work on most LBCs .65 Ford Mustangs and others .I've sold many units over the years to club members and on e-bay. I'm getting too old and can't see well enough to keep building these.
